8 Laboratory testing lightning
and surge protection components
In the BET Test Centre, lightning and surge protection
components, lightning protection structures and surge
protection devices are put through their paces by
highly qualified specialists accordance with the rel-
evant standards.
The BET possesses test generator for lightning cur-
rent tests 200 and hybrid generator for
surge current tests kV.
Tasks performed include developmental tests new
developments and modifications OBO surge pro-
tection devices according the testing standard IEC
61643-11. The tests for lightning protection compon-
ents are carried out according IEC/EN 62561-1
and those for spark gaps according IEC 62561-3.TBS

BET test generator BET SO2
testing system
1.
The hybrid generator used for testing data cable
protection devices accordance with IEC 61643-21
"Surge protective devices connected telecommunic-
ations and signalling networks".
The following standard-compliant tests can car-
ried out:
• Lightning protection components 62561-1
• Spark gaps 62561-3
• Holder 62561-4
• Insulated components IEC 62561-8
• Lightning current meters 62561-6
• Surge protection devices 61643-11
• Data cable protection devices 61643-21
• Environmental testing ISO 9227 (neutral
continuous salt spray testing)
• Environmental testing 60068-2-52 (cyclical
salt spray testing)
• Environmental testing ISO 6988 (SO2
toxic gas testing)
• protection rating 60592
• Tensile strength 10002-1
However, customer-specific requirements and tests
not covered standards can tested the fol-
lowing parameters:
• Lightning current pulses (10/350) 200 kA,
100 and MA²s
• Surge current pulses (8/20) 200 kA
• Combined surges (1. addition, the impact events in-
volving lightning scientifically investigated.2/50) kV
• Combined surges (10/700) kV
• Follow current system 255 Hz, kA
• Insulation measurement AC, and
up DC
• Conductivity measurements Hz
• Tensile and compression strengths 100 kN
